COMO 1085 é o padrão australiano para materiais de trilhos ferroviários – Trilhos, que especifica os requisitos aplicáveis aos carris de aço utilizados nas vias férreas, incluindo a composição da liga, propriedades físicas, e dimensões. Também inclui requisitos para controle de qualidade, teste, e certificação.
BHP RT STD, Por outro lado, é um padrão estabelecido pela mineradora e metalúrgica BHP (anteriormente conhecido como Broken Hill Proprietary) para trilhos utilizados em sua própria rede ferroviária, but it is also widely used in other Australian railways. It sets out similar requirements to AS 1085 in terms of material properties and dimensions, but with some differences in the manufacturing process and finishing of the rails.
The railway rail standard AS1085 includes flat-bottomed rails (Type A) and grooved rails, also known as vignole rails (Type B). Flat-bottomed rails are typically used in slower speed and lighter trafficked areas, while grooved rails are used in higher speed and heavier trafficked areas.
Vignole rail, also known as flat-bottom rail or flanged T rail, is a type of railway track rail design that was invented by the French engineer Charles Vignoles in the mid-19th century. This design consists of a flat base with an upright flange on either side to guide the wheels of the train.
The Vignole rail design is commonly used in modern railways around the world due to its ease of manufacturing and maintenance. The flat bottom ensures that the rail can be easily attached to sleepers or ties with fasteners, while the upright flanges keep the train wheels aligned.
The Vignole rail design has become a standard in the railway industry, providing a reliable and efficient solution for constructing railway tracks.
The railway rail standard AS1085 specifies a range of requirements for railway rails used in Australia, including the following:
1. Material requirements, such as chemical composition and mechanical properties
2. Physical dimensions, such as rail length, peso, and cross-sectional profile
3. Tolerances and deviations from specified dimensions
4. Surface defects and imperfections, como rachaduras, Voltas, and splits
5. Markings and identification of rails
6. Testing and inspection procedures
7. Acceptance criteria for rails based on test results.
These specification requirements are intended to ensure that railway rails used in Australia meet the necessary safety and performance standards for railway operations.
The railway rail standard AS1085 is used in Australia for the design, fabricar, and maintenance of railway tracks. It covers a wide range of applications including heavy haul rail, urban transit systems, industrial rail facilities, e outras infraestruturas ferroviárias. AS1085 specifies requirements for rails made from different materials including steel, iron, and other alloys used in rail construction. It also defines the physical dimensions, Tolerâncias, and testing procedures necessary to ensure that the railway rails meet the necessary safety and performance standards for the specific application. Portanto, AS1085 is an important standard for the railway industry in Australia.
